Description

Technical Field

[0001] The utility model relates to the technical field of casting molds, in particular to a casting mold for a cylinder head. Background Technique

[0002] A casting mold refers to making the structural shape of a part in advance with other materials that are easy to form, and then placing the mold in a sand mold. Thus, a cavity with the same structural dimensions as the part is formed in the sand mold. Then, a fluid with fluidity is poured into the cavity. After the fluid cools and solidifies, a part with exactly the same shape and structure as the mold can be formed. The casting mold is an important part of the casting process.

[0003] When a cylinder head is produced, a corresponding casting mold is required. When the existing casting mold is in use, the upper and lower molds are fixed with bolts. After casting is completed, external tools are needed to remove all the bolts to cancel the fixation between the upper and lower molds, making the disassembly between the upper and lower molds rather troublesome and reducing the use efficiency of the device. Therefore, the utility model provides a casting mold for a cylinder head. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a casting mold for a cylinder head to solve the problems raised in the above background technique.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A casting mold for a cylinder head, including a lower mold and an upper mold. A pouring port is arranged at the top of the upper mold. Fixing blocks are fixedly installed on the front side and the rear side of the upper mold. A limiting groove penetrates through the surface of the fixing block. Fixing sleeves are fixedly installed on the front side and the rear side of the lower mold. An installation sleeve is fixedly installed on the surface of the fixing sleeve, and the installation sleeve is communicated with the fixing sleeve. An elastic component is arranged inside the installation sleeve. A limiting block is arranged inside the installation sleeve through the elastic component. A sliding rod is fixedly installed on the surface of the limiting block. A moving plate is fixedly installed on the surface of the sliding rod. A slot is formed on the right side of the moving plate. A sliding component is arranged on the right side of the installation sleeve. A plug rod is arranged on the right side of the installation sleeve through the sliding component. Positioning components are arranged on the left side and the right side of the upper mold.

[0007] Preferably, the elastic component includes an installation plate arranged on the inner wall of the installation sleeve. A spring is fixedly installed on the side of the installation plate close to the fixing sleeve, and the spring is fixedly connected with the limiting block. The sliding rod is slidably connected with the installation plate.

[0008] Preferably, the sliding component includes a support plate disposed on the right side of the mounting sleeve. A slide rail is fixedly installed on the surface of the support plate.

[0009] Preferably, the positioning component includes mounting blocks disposed on the left and right sides of the upper mold. A positioning rod is fixedly installed at the bottom of the mounting block. A positioning sleeve is slidably connected to the surface of the positioning rod, and the positioning sleeve is fixedly connected to the lower mold.

[0010] Preferably, a first handle is fixedly installed on the top of the upper mold, and second handles are fixedly installed on both the left and right sides of the lower mold.

[0011] Preferably, the limiting block has a right-angled triangle structure and is made of a metal material.

[0012] Preferably, the slider has a T-shaped structure and is made of a metal material.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: For this cylinder head casting mold, when the upper mold moves downward to fit with the lower mold, during the downward movement of the upper mold, the fixed block will be inserted into the fixed sleeve, and the fixed block will contact the limiting block and squeeze the limiting block, causing the limiting block to move outward through the sliding rod. When the upper mold and the lower mold are in fit, at this time, the elastic component just makes the limiting block move inward and insert into the limiting groove to limit the fixed block. After the cylinder head is formed by casting, pull the moving plate outward to make the sliding rod and the limiting block move outward to a suitable position, so that the insertion rod moves leftward along the sliding component and inserts into the insertion slot. Then the moving plate can be released, and then make the upper mold move upward to separate from the lower mold, achieving the goal that the device can be installed and disassembled more conveniently, improving the use efficiency of the device and the practicality of the device.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Refer to Figures 1-4, a cylinder head casting mold, comprising a lower mold 1 and an upper mold 2. A pouring port 3 is provided at the top of the upper mold 2. Fixed blocks 4 are fixedly installed on both the front and rear sides of the upper mold 2. A limiting groove 5 penetrates through the surface of the fixed block 4. Fixed sleeves 6 are fixedly installed on both the front and rear sides of the lower mold 1. An installation sleeve 7 is fixedly installed on the surface of the fixed sleeve 6, and the installation sleeve 7 communicates with the fixed sleeve 6. An elastic component is arranged inside the installation sleeve 7. A limiting block 10 is arranged inside the installation sleeve 7 through the elastic component. The limiting block 10 is in a right triangle structure and is made of a metal material, facilitating the limiting block 10 to have higher structural strength and be more durable. The elastic component includes an installation plate 8 arranged on the inner wall of the installation sleeve 7. A spring 9 is fixedly installed on the side of the installation plate 8 close to the fixed sleeve 6, and the spring 9 is fixedly connected to the limiting block 10. A sliding rod 11 is slidably connected to the installation plate 8. When the limiting block 10 moves outward, the spring 9 is compressed. When the limiting block 10 loses the force to move outward, the acting force generated by the compression of the spring 9 causes the limiting block 10 to move inward, thus facilitating the limiting block 10 to be inserted into the limiting groove 5, and thus facilitating the limitation of the fixed block 4. A sliding rod 11 is fixedly installed on the surface of the limiting block 10, and a moving plate 12 is fixedly installed on the surface of the sliding rod 11. A slot 13 is opened on the right side of the moving plate 12. A sliding component is arranged on the right side of the installation sleeve 7. A plug rod 17 is arranged on the right side of the installation sleeve 7 through the sliding component. The sliding component includes a support plate 14 arranged on the right side of the installation sleeve 7. A slide rail 15 is fixedly installed on the surface of the support plate 14. A slider 16 is slidably connected inside the slide rail 15. The slider 16 is in a T-shaped structure and is made of a metal material, facilitating the slider 16 to only move along the slide rail 15 and avoiding the phenomenon that the slider 16 will fall off the slide rail 15. And the slider 16 is fixedly connected to the plug rod 17, facilitating the plug rod 17 to only move left and right along the slide rail 15 through the slider 16, and facilitating the plug rod 17 to limit the moving plate 12 when inserted into the slot 13 and prevent the moving plate 12 from moving inward. At this time, after releasing the moving plate 12, the moving plate 12 will not move inward, thus facilitating the disassembly between the upper mold 2 and the lower mold 1 to be more convenient. Positioning components are arranged on both the left and right sides of the upper mold 2. The positioning components include installation blocks 18 arranged on both the left and right sides of the upper mold 2. A positioning rod 19 is fixedly installed at the bottom of the installation block 18. A positioning sleeve 20 is slidably connected to the surface of the positioning rod 19, and the positioning sleeve 20 is fixedly connected to the lower mold 1. When the upper mold 2 moves downward, the positioning rod 19 is inserted into the positioning sleeve 20, facilitating the positioning installation of the upper mold 2, and thus facilitating the fixed block 4 to be inserted into the fixed sleeve 6 more precisely. A first handle 21 is fixedly installed at the top of the upper mold 2. Second handles 22 are fixedly installed on both the left and right sides of the lower mold 1. For this cylinder head casting mold, when the upper mold 2 moves downward to fit with the lower mold 1, during the process of the upper mold 2 moving downward, the fixed block 4 will be inserted into the fixed sleeve 6, and the fixed block 4 will contact the limiting block 10 and extrude the limiting block 10.The limiting block 10 is moved outwards through the sliding rod 11. When the upper die 2 is in contact with the lower die 1, at this time, the elastic component just makes the limiting block 10 move inwards and insert into the limiting groove 5 to limit the fixed block 4. After the cylinder head is formed by casting, the moving plate 12 is pulled outwards, so that the sliding rod 11 and the limiting block 10 move outwards to a suitable position, so that the inserting rod 17 moves leftwards along the sliding component and inserts into the inserting slot 13. Then the moving plate 12 can be released. Then the upper die 2 is moved upwards to separate from the lower die 1, achieving the goal that the device can be installed and disassembled more conveniently, improving the use efficiency of the device and the practicability of the device.

[0021] During use: The upper die 2 is moved downwards through the first handle 21, so that the positioning rod 19 is inserted into the positioning sleeve 20 until the upper die 2 is in contact with the lower die 1. During the process of the upper die 2 moving downwards, the fixed block 4 will be inserted into the fixed sleeve 6, and the fixed block 4 will contact the limiting block 10 and squeeze the limiting block 10, so that the limiting block 10 moves outwards through the sliding rod 11, compressing the spring 9. When the upper die 2 is in contact with the lower die 1, at this time, just through the acting force generated by the compression of the spring 9, the limiting block 10 moves inwards, so that the limiting block 10 is inserted into the limiting groove 5 to limit the fixed block 4. The casting solution is poured into the mold cavity formed by the upper die 2 and the lower die 1 through the pouring port 3. After the cylinder head is formed by casting, the moving plate 12 is pulled outwards, so that the sliding rod 11 and the limiting block 10 move outwards, compressing the spring 9 until the moving plate 12 moves outwards to a suitable position. Then the slider 16 is moved leftwards, so that the slider 16 moves leftwards along the slide rail 15, making the inserting rod 17 move leftwards and insert into the inserting slot 13. Then the moving plate 12 can be released. Then the upper die 2 is moved upwards through the first handle 21 to complete the disassembly between the upper die 2 and the lower die 1.
